CHIMNEY.

Specification of Letters Patent.

Application filed May 24, 1913.

Serial No. 769,656.

To all whom it may concern 1 Be it known that 1, JAMES H. McKAY, a citizen of the United States, residing at Forest City, in the county of Vinnebago and State of Iowa, have invented new and useful Improvements in Chimneys, of which the following is a specification.

This invention relates to chimneys for dwellings and other buildings, and it has for its object to provide a simple and eflicient construction whereby moisture leaking through the joint between the chimney and the roof will be deflected from the chimney and disposed of, thereby avoiding injury to the interior finish of the building.

A further object of the invention is to produce a simple and eflicient moisture catching device permanently associated with the chimney.

A further object of the invention is to produce a simple and efficient moisture catching device forming a permanent part of the chimney structure and having a discharge spout whereby the moisture is deflectedand disposed of.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,Figure 1 is a View in elevation of a portion of a chimney equipped with the invention, showing also in section a portion of the hip roof through which the chimney extends. Fig. 2 is a horizontal sectional view taken on the line 2-2 in Fig. 1. Fig. 3 is a sectional View, enlarged, taken on the line 3-3 in Fig. 2. Fig. 4 is a sectional detail view taken on the line 44 in Fig. 2.

Corresponding parts in the several figures are denoted by like characters of reference.

The chimney 5 is of ordinary brick construction, the brick being laid in courses separated by layers of mortar 6. The chimney has been shown as extending through a roof 7 on which, for purposes of illustrapiojii, several courses of shingles 8 have been Mounted on the chimney a suitable distance below the roof, but relatively close thereto, is a circumferential substantially horizontal trough 9 which may be constructed of sheet metal, such as tin proper, sheet iron or the like, which may be protected against corrosion by galvanizing, painting or any other well known manner, and which is capable of being soldered in the customary manner to form a trough of the desired shape, said trough being made to surround the chimney on the four sides thereof. The trough 9 is provided at its inner edge with a circumferential lip 10 extending inwardly into the mortar between two courses of brick. The trough will thus be firmly supported in position surrounding the chimney and in such a manner that all moisture leaking through the joint between the chimney and the roof must of necessity be guided into the trough. The latter is provided at one side thereof with a spout 11 which extends through the roof and which is slightly inclined so that water will be conveyed over said spout on to the surface of the roof, said spout being provided with a terminal lip 12 which may be nailed or otherwise secured on the roof.

It will be seen from the foregoing description that I have provided a construction whereby water entering through the joint between the chimney and the roof must of necessity be intercepted by the circumferential trough from which it is directed through the spout 11 on to the outer surface of the roof over which it is conveyed to the customary drainage gutter or spout, not shown. When a chimney is not protected and when the joint between the chimney and the roof is imperfect, as is frequently the case, moisture entering through said joint is apt to trickle down the chimney and be thus conveyed into the rooms of the building, oftentimes causing great injury to the plastering and papering of such rooms. By this invention any such possibility is avoided, the device of the invention being of itself simple in construction, inexpensive and easily applied.

The use of this invention will, of course, not interfere with the use of protection strips of tin or sheet metal, such as are usually nailed or otherwise secured on the Patented Sept. 15, 1914.

roof surrounding the chimney, but inas-- much as such protection strips 1are, well; known and of common use they have not been indicated in the drawing.

Having thus described the invention-,- what is claimed as new, is:

1. A brick chimney, a roof through which v the chimney extends, a substantially hori-v zontal trough surrounding the chimney a short distance below the roof, said troughhaving a circumferential lip extending inwardly between two courses of brick, and an inclined spout extending from the trough through the roof and dischargingexteriorly on the latter.

2. A chimney constructed of brick set in" Copiesof this patent maybeobtained for a substantially horizontal trough surrounding the chimney a short distance below the roof and having a circumferential lip extending inwardly into the mortar between two layers of brick, and a discharge'spout extending from the trough through the roof and having a terminal lip connected therewith.

e In testimony whereof I afliX my signature in presence of two witnesses.
